YouTube Comment about the official video:
“The video is not dumb. It is about a boy who suffers alot, and decides to stop listening too all the evil things in this world. The random places he finds himself in later represent his thoughts drifting away from the place where he is at (sadness). His thoughts lead him to the monster in the cave, the root of all evil (as the myth goes). It is not a sad ending because the two other ”men” leave as soon as they know he can handle the monster by just covering his ears and yelling la la la.” Jay Flores
Another even more interesting and detailed explanation (read after viewing!). http://creepypasta.wikia.com/wiki/Bolivian_Tradition
